I can relate to the losing hair part. My hair is falling out in handfuls in the shower, too, and it's all over the house I know it's a common thing to happen after giving birth, though, so I don't really mind.

I think I also put on a little weight after Simon was born. I was really hungry when he went through his growth spurt at 6 weeks. Since then I seem to be almost back to my pre-birth weight. Anyway, I'm sure the weight will be fluctuating for a while.

Maybe take a test if you're worried about it just to be sure either way?

I've taken 2 pregnancy tests since Luka was born, since I've had 2 periods, but with a long time in between them (6 and 14 weeks PP). I remember the same thing happening when my first was a babe. I would just die if I got pregnant now!
For now, since the pregnancy scares, we are using condoms and/or withdrawal, but I have an appt. at Planned Parenthood to get an IUD. We definitely don't want another baby for a while (4-5 years, if ever). I am not good at taking pills (I can never finish a 10 day antibiotic in less than 2 weeks!), and condoms are expensive and my partner doesn't like them. I would prefer to get the hormone free Paragard IUD (which lasts up to 12 yrs!) but since I have VERY heavy periods, I need the Mirena which only lasts 5 yrs. and has a small amount of hormones in it to reduce bleeding and cramping.
